World 1-4 (Super Mario 3D Land)
From the Super Mario Wiki
World 1-4 is the fourth course of World 1 in Super Mario 3D Land. It is an athletic course, and its gimmick is controlling a platform that moves forward or backward depending on where the player stands. This level can be accessed by collecting 3 Star Medals. The course's icon is a Switchboard circling a rock spire with some blocks above it.
Mario starts on the land with a Switchboard. Mario must go up on this platform and move it ahead. In the way, there are a ? Block, Coins, Paragoombas, a water geyser and some Brick Blocks. The trail ends in a mountain with the Checkpoint Flag. Another Switchboard must be used briefly to reach in another, dodging fireballs from a Fire Piranha Plant. The last Switchboard takes Mario to a mountain with ? Blocks and a Mystery Box. Soon after, there are some water geysers. The last two are for launching the Switchboard to far below rails that take Mario to a Warp Pipe. The Warp Pipe connects this area to the end of the level, where Mario can use one of these platforms to grab the top of the Goal Pole.
